citada

Citada is the feminine singular past participle of the Portuguese verb citar, meaning "cited" or "quoted." In use, citada functions as an adjective or a part of a compound grammatical form to indicate that something has been referred to or mentioned in a text.

Etymology and grammar: Citada derives from citar, which comes from Latin citare. Portuguese adjectives and past participles agree in gender and number with the noun they modify, so citada corresponds to feminine singular nouns (for example, "a teoria citada" or "as fontes citadas").

Usage: In academic and formal writing, citada is commonly employed to designate sources, ideas, or passages that have already appeared in the work or in a referenced document. Examples include "a teoria citada na introdução" (the theory cited in the introduction) and "as fontes citadas no capítulo 3" (the cited sources in chapter 3). The masculine form is citado, and plurals are citados (masc.) and citadas (fem.).

See also: Citando, citação, citar, fontes citadas. While citada is primarily a grammatical form, it may appear in bibliographic contexts, footnotes, and quotation practices to indicate prior reference to a source.

Note: Citada is rarely used as a proper noun or place name; it is mainly encountered as a language element in Portuguese texts.
